Defender believes the European Champions can go far...
The Spanish were the bookmaker's favourites to lift the crown coming into the competition, having been on an outstanding run of form.
However, they suffered a severe shock as they lost 1-0 to Switzerland in the first Group H game - only the second defeat in an incredible 49 matches for the European champions.
Despite being left with a difficult task to qualify for the knockout stages, Vincente Del Bosque’s side recovered to show their pedigree by beating Honduras 2-0, and ending Chile’s 100 per cent start to the competition with a 2-1 victory.
And after topping the group to set up a mouth watering clash against near neighbours Portugal in the last 16, Capedevila believes the side are ready to peak.
"We've shown we've overcome the blow of the first game, and now the squad is more united than ever, with morale pretty good," Capedevila told the Spanish football federations website.
"We've done well to be able to win and get through as group winners. Now we are playing Portugal, which will be a very nice tie. We've recovered from the psychological blow, which was the hardest thing to do.
"We didn't have any doubts about our play or our qualify, but it was crucial for us to recover mentally and now we're strong."
The Villareal defender also praised the team’s forwards, despite their disappointing return of four goals from three games.
"It's great to play with players like [David] Villa, [Fernando] Torres, [Fernando] Llorente. We have some of the best strikers in the world," he added.
